y known that I, lVlnnUnN'iN. DENNISQN, citizen of,l tl1e United States, residing at the boioi'lgh of lvlerchantville, in the county of Camden and State ofNew Jersey, have invented certain new and useful Improve! meritsin" a Combined Speed Regulator and Brake, of which the following isa full, clear, and complete"disclosure, reference being had to the accompanying drawings, formlng a part o f this specification.

My invention relates to speed regulators andflu'akes,and particularly to that class of the v.same "which are usedto regulate the speeds of talking machines.

Talking machines are usually provided witlrspeed regulators, and also with separate speed brakes which are used only in starting and stopping the machines, for while some of the speed regulators in use are capable of actingas braketo start and to stop the macl'nne, yet these regulators cannot be" used bforthis purpose without changin the adjustment- -of the regulator which units the rate of speed, oj'ffuthe machine, and when so used ,iti iswnecessiry to readjust the regulator after startin" Q einachine to obtain the dei are@ speed. l f t -The main b1e`ct-S of my invention are to provide a regulator of few artsand simple and inexpensive `design an which will be durable and letlicient in use; to provide a nregulator? which may be actuate quickly andlco'nveniently to start or stop the machine and"whichifiiiay be quicklyand easily adjuste'tl'i to" lilnitthes )eed of theymachine `to any' predetel'niiiietl rate; to provide a regulator which may be adjusted to limit the 'speedfwof thenlachine vto any predetermined "rafte, and which may also befusulv as" a` brake to start.` and to stop the machine, without V disturbing the adjustment" which. fixes "the `limit 'of the rate of speed; and to i 'therfiin )'ioveinentswhich willapy ai @twang in bien@ maar bung mii/ea away Aandthe cabinetbeiiigfshown a" fragmeni "ltlotoi and fraiile' detached from 'the ca'liineb; and Figs. 3 and 4 are views of parts of the `applimnmV md August 2 7, isos; serial No. ss2,o9e l withfthe friction disk.

Referring to`A the` drawings, `the motor frame l has depending therefroniahone side, the-,motor 2 which rives aworm gear 3 meshing with the worm 4,011 the turn table shaft 5, the upper end of which is adapted 6o to receive the :turn table of, the talking machine. The motor' thus far described may be of any well known type andfurther description thereof is therefore not necessary. 0n the turn table shaft 5 is mounted ay worm gear 6 whicht meshes with aworm 7 on the inclined governor shaft 8, wlliclllatter the end bearings 9 The bearing 9 is secured tothe top 70 plate of the frame' and the bearing 1 0 to theI lower en d of the depending arm.-10. The,r governor is of the centrifugal type, the governor shaft 8 having the 'expansible arms 11 carrying the fly balls 12. v The outer ends 75 of the arms 1 1 are mounted upon ac 'olla1 13 to which is attached a friction disklt",A the said collar and disk being free tofreciprocate on theshaft 8. The o posite `vends4 o thev arms 11 aresecured to tie governor 8 0 f shaft 8, as usual. To `regulate thespeed of the gevel-nora bell crank having arms 15`a11d 16,' is mountf. v ed to swing onv the lower end of a post W17, depending from the top plate of the frame of the motor and the outward movement of the "arm 16 and the inward movement ofthe arm are resisted by the` pressure of the spiral spring 17 snrroundiner the post 17, one end of the spring being fastenedtothe l, latter and the other end to the bell crank lever. feltf. or.`

Afriction pad 1S, made of any other suitable",inaterial, is mounted`o n 1 the end of the arm15`\vhieh is arrangedtobring the pad into and 'ot of engagement The face ofthe said disk being transverse to' the plane of the mainfportion of the .actuated pinv L2, the latter having. itsouter V27 and' is jexpanded'upon the pin 22, thus :effecting va tight engagement with the screw threaded portion thereof. In the exterior 4'wall 28 of one side of the cabinet is 'an orifice 29, over` which fits a plate struck'up upon which is an arc of a circle iaving a radius. 'Y Substantially equal to the effective length lof the pin`22, is a raised portion 30 having a circular aperture 31 therein, adapted to receive the lug 26 of the nut, but too small to receive the shank thereof. Extending laterally froml the aperture 31 and communicating therewithis an elongated slot 32 adapted to receive the pin 22 but too small s in diameter to receive the lug 2G of the nut.

4The operation of the device is as follows: Assi'iming the regulator to be in the position indicated in full lines in the drawing, to start the motor the thumb nut is grasped bythe milled head and drawn outwardly until the lug 26 of the' nut is withdrawn v from the aperture 31, when the nut is then swung tin the dotted lines in Fig. 1.

--the effective length of laterally carrying the pin through the slot 32,.and the nut is then released, Wherelipon the'lug 26 of the nutwill be held rigidly against' the outer surface of the raised portion 30 of the plate 30, thus lock- ,ing the pin and lever in the position shown This movement of the nut releases the friction pad 4 rom engagement withthe friction disk, and the motor, thus released, begins to revolve, the governor shaft carrying the friction disk and fly balls therewith, advancing the friction disk towardthe friction pad in proportion to the incrase of speed, 'as usual. When the disk reaches thefriction pad 15, in its dotted line position, the disk is'held bythe pad against further advancement but continues to revolve subject to the resistance of the pad which limits the speed of the disk to a fixed rate.

A variation of the rate of speed .of the governor maybe accomplished by adjusting th'elliiit upon its threads to change the longize -tudinal position of the pin,

vvtion pad will be moved toward or away from 'into lockingengagemeut in the aperture whereby the fricthe'friction disk, thus decreasing or increasing the speed of the disk accordingly. The

adjustment of the nut longitudinally of the pinv may be made to such an extent as to entirely stop the motor but ordinarily the stop- :of the motor is accomplished by the quicker action of the pin and nut together, without rotating thenut, by swinging the lniit laterallyA and permitting the inner reduced end of the shank of the/nut to drop the pin 22 by rotating i vengage said as liereinbefore described, and the nut is rotated only when it is desired to change the rate of speed of the governor.

Vith this construction in mind it is evident that I have provided an extremely simple device which may be adjusted to limit the speed of a talking machine to any predetermined rate by the movement of a single actuating element, and whereby the machine may be started or stopped by the action of the same element without Achangingthe adjust-ment of that Aelement with respect to the said rate of speed.

Although I have shown only one form in which this invention may be embodied it is obvious ,that many changes might be made in the construction herein set forthwithin the scope of the appended claims without departing from the spirit of this invention or sacrificing any of the advantages thereof.A
